â€śWe are now working on witnesses,â€ť stated a senior police officer from the Directorate of Criminal Investigations(DCI) department.

Dominic Kamau is being sought by police officers for questioning as to why his Identification Card(ID) was used by Irungu to gain access to the 29 year-oldâ€™s apartment.

DNA results from other suspects who are Jacque Maribe and Brian Kasaine are yet to be released to establish if they were involved in the murder.

Police officers have pointed out that they have planned to take the probe into Juba, South Sudan to gain more information about the deceased.
